Description

  INDUSTRIAL APPLICABILITY The present invention provides an exterior insulation building suitable for attaching exterior materials such as tiles, stone plates, panels, or various boards to a wall of an RC exterior insulation building after properly adjusting the unevenness. The present invention relates to an exterior material fixture.

  Conventionally, in the case where particularly large tiles are attached to the wall surface of an RC building, an attachment structure as proposed in Patent Document 1 or 2 has been generally employed.

  This mounting structure is composed of a support plate that is a plate-like member bent in an approximately L shape, and a connection plate that is attached to the support plate and supports tiles. The support plate is configured to join the upright portion to the wall surface of the RC building and fix it with an anchor bolt. The upright portion has a longitudinally long hole that is aligned with the coupling hole that is open on the wall surface, and an anchor bolt is inserted and fixed to the elongated hole. Is. As described above, the elongated hole in the upright portion is a longitudinally elongated hole and can be adjusted in the height direction.

  The connecting plate is composed of a horizontal portion and a locking piece portion configured to be upright at the tip thereof, and the horizontal portion is put on the horizontal portion of the support plate in a joined state, and the latter is formed into a long hole extending in the former non-landing direction. The long holes in the horizontal direction or the long holes in the horizontal direction are made to correspond to each other and adjusted in the non-landing direction and the horizontal direction, and then fixed in the adjusted connection state with screws.

  The tiles are supported by a locking piece at the tip of the connection plate in a support manner according to the configuration.

  In the large tile mounting structure proposed in Patent Document 1 or 2 having such a configuration, the horizontal portion of the support plate is mounted in a protruding state from the wall surface of the RC structure, and the horizontal portion of the connection plate is not flat. In this case, the protrusion length of the horizontal portion of the support plate that is protruded in advance must have a certain length from the viewpoint of securing a necessary adjustment width. . As a result, there is a problem that the distance between the back surface of the exterior material such as tiles and the wall surface of the RC structure becomes too wide.

  Further, as described above, the support plate has its upright portion joined to the RC wall surface and fixed with an anchor bolt inserted into the longitudinal elongated hole. Although it is possible, even if it is fixed with anchor bolts, there is a risk that it will loosen due to shaking such as an earthquake within a long period of time, and may gradually fall due to the vertical load of exterior materials such as tiles .

  Patent Document 3 is proposed by the present applicant for the purpose of solving the problems of the inventions of Patent Documents 1 and 2 described above, and this is fixed to the surface of the frame of an RC building by fixing means.

And an exterior material mounting tool configured with a support portion of the exterior material configured on the tip side of the adjustment support bolt.

  Further, in the above exterior material mounting tool, a support plate for fixing the support portion of the exterior material to a tip of the adjustment support bolt, and a support fitting fixedly attached to the front surface of the connection plate, the tiles And a support bracket that constitutes a locking piece for locking the height of the support bracket so that it can be attached to the coupling plate with screws while adjusting the height while corresponding to the coupling hole. An adjustment slot that is long in the vertical direction, and a fixed fixing hole that is fixed to the coupling plate with a tapping screw after being attached to the coupling plate with the adjustment slot and screws.

  Therefore, according to the exterior material fixture of the invention of Patent Document 3, when this is attached to the surface of a building frame with the attachment member, the adjustment of the unevenness of the exterior material such as tiles attached to the support portion is performed. The adjustment support bolt can be easily adjusted by adjusting the screwing state of the mounting support member with the screwing support portion. At this time, the rear end side of the adjustment support bolt is made to enter the entry space formed in the RC structure on the back side of the exterior material fixture so as to be able to advance and retreat. The protruding length of can be reduced. Therefore, the problem that the distance between the back surface of the exterior material and the wall surface of the RC structure becomes too wide can be solved.

  Furthermore, according to the exterior material fixture of the invention of Patent Document 3, a support fitting (a part of the support part) for attaching the exterior material is tapped to a coupling plate (a part of the support part) attached to the tip of the adjustment support bolt. Since it is configured to be fixed with screws, there is no possibility that the support metal fitting to which the exterior material is attached will gradually fall on the coupling plate even after a long period of time.

  However, the mounting material or mounting structure of the exterior material according to any of the inventions of Patent Documents 1 to 3 described above applies a support plate or a mounting member, which is a metal member, to the surface of the RC building body for the mounting. They are fixed in contact with each other, and their installation constitutes a thermal bridge that conducts the temperature inside and outside the building mutually. The invention of Patent Document 3 is an improvement of the inventions of Patent Documents 1 and 2 in terms of the above points, and is excellent in that respect, but is similar in terms of forming a thermal bridge. It should be said that the invention has a configuration suitable for buildings. None of these are applicable to buildings with external insulation.
